A combined cycle wherein part of the gas turbine exhaust gas stream is recycled to the gas turbine and the remainder of the gas turbine exhaust gas stream is expelled from the cycle. The power output of the combined cycle is increased by increasing fraction of gas turbine exhaust gas that is recycled to the gas turbine and the power output of the combined cycle is reduced by reducing the fraction of gas turbine exhaust gas that is recycled to the gas turbine.
